Nintendo's best selling IPs are Mario, Pokémon and Zelda.
Mario has gotten Mario Galaxy and New Super Mario Bros.
Pokémon has gotten Pokémon Diamond/Pearl and Platinum.
Zelda has gotten Twilight Princess and Phantom Hourglass, and now Spirit Tracks is upcoming.
Your assumption is wrong. Nintendo may have abandoned some of their popular IPs(I don't think they have, but I can see why some people might), but they have by no means abandoned their best selling IPs.
